Solidago 'Solar Cascade'

Goldenrod

Flowers in axillary clusters

Not an aggressive runner

Extremely drought tolerant

Delightful, golden-yellow flowers are borne in axillary clusters along reflexing stems from late summer into fall. Reliable, deep green, glossy foliage remains clean throughout the growing seasons. Not an aggressive runner, 'Solar Cascade' is a clump forming perennial reaching knee height, maxing out somewhere between the taller 'Fireworks' and more compact 'Golden Fleece'. Performs best in moist to average garden soil under full sun or partial shade; extremely drought tolerant once established. This great garden plant is easy to propagate and proved to be a standout in The Cincinnati Zoo and Botanical Garden perennial trials. Plant en masse for a dramatic effect or incorporate into seasonal arrangements.

Goldenrod Interesting Notes

Convincing gardeners to grow goldenrods is a bit like trying to sell Toyotas in Detroit, but I will continue anyway. They are certainly ubiquitous in the fall landscape and are still wrongly accused of causing hayfever. Therefore, it bears repeating that goldenrods, like aster, Joe-Pye, ironweeds, and all the Composites, are insect-pollinated, so their pollen is heavy and sticky in order to facilitate transfer by our six-legged friends. It is the wind-pollinated plants like grasses, ragweed and many trees (I am allergic to maples for example) that produce the great quantities of light, airborne pollen that get into our noses and throats and cause the immune reaction known as hayfever. There are goldenrods for every situation, and if you avoid the aggressively weedy species like S. canadensis (My apologies to Canada) and S. graminifolia, they are agreeable garden subjects at home in the border, meadow, rock, or shade garden. Once I started to learn the different species, I became more and more aware of their subtle differences and convinced of their important role in native ecosystems as soil stabilizers and sources of food and shelter for wildlife. They are beautiful in leaf and flower, too, and no wildflower garden is complete without a few of our hundred or so species scattered around. - William Cullina, The New England Wild Flower Society Guide to Growing and Propagating Wildflowers, p. 197
